Scientific and Toxicity Study of Pueraria mirifica

A series of studies involving breast cell lines and the activity of Pueraria mirifica in vitro have been performed by the Emory University School of Medicine in Atlanta, Georgia, USA, and the Department of Obstetrics and Gynecology, Phramongkutklao College of Medicine, Bangkok, Thailand. These studies have shown that Pueraria mirifica root extract (Smith Naturals Co Ltd., Bangkok) has potent anti-estrogenic properties against aggressive cell cancer lines in vitro, especially the proliferative estrogen receptor-positive (ER+) breast cancer lines (T47-D, MCF-7, and ZR-75-1) obtained from the MD Anderson Cancer Institute (Texas) and the National Cancer Institute (NCI) at the U.S. National Institutes of Health (NIH).

Pueraria mirifica and Women

Most women are very concerned about aging, particularly the effects brought about by the aging process. At a certain age, the body experiences dramatic changes: the body's systems and its functions begin to decelerate and the immune system weakens. For the average woman, menstruation cycles end at 48-50 years of age when the reproductive system stop or slow down functioning. Moreover, it is a fact that women whom no longer menstruate are further troubled by the adverse effects of lower levels of estrogen in the body. Estrogen helps to control the production of free radicals (free radicals are perceived as being harmful for the body because it accelerates degeneration of bodily organs), and therefore lack of estrogen will induce production of free radicals. Consequently, menopausal women will experience both psychological and physiological changes. Psychological changes range from anxiety, tension and nervousness to chronic depression. Whereas the physiological affects include hot flushes, fatigue and insomnia to more severe conditions as bone loss, balding and degeneration of the reproductive area. Pueraria mirifica contains substances that can effectively cope with these problems.
